Dortmund played quite well in their previous Champions League match against Manchester City, allowing only one goal off of a penalty shot, but their loss to Schalke 04 will be the motivating force entering tomorrow's match.

Real Madrid's lineup changes serve as extra inspiration, as they only have three fit defenders at the moment.

Dortmund's problem, however, isn't in getting to Madrid's back line. It's getting past their front men to diminish any explosive attacks.

Real Madrid's front men include Cristiano Ronaldo, MesutOzil, Angel Di María and Gonzalo Higuain and Benzema. All have produced well for the team so far.

Ronaldo has already scored nine goals in eight games played. Ozil and Di Maria both have one assist, and Higuain and Benzema have five goals between them.

This is a deep front line, and they can more than make up for their lack of defensive help.
